With that quad core and card and no gaming at all on the PC. You really do not need to upgrade anything. But to answer your question you can run HD4xxx or higher series card. The only thing is if your PCIe x16 slot is version 1.x don't get a version 2.1card have had problems in older slots, version 2.0 works fine.
